I don't know how long its been there, but yesterday I noticed a new option in my Canvas Calendar, next to Assignment and Event. Its called "To Do," but I seem unable to actually create a To Do item. I click Submit, it appears to attempt to save... and then it stays on this window. I looked at Instructure's How do I use the Calendar as an instructor?, but it doesn't seem to talk about this new thing. Or I'm on the crazy sauce. Anyone else see this option, and is it working for you?
